What does 20 require?

Any lighting associated with a public transport facility in premises or infrastructure must be provided to a level appropriate to the location that enables tasks to be completed safely. On buses, coaches, ferries, trains, trams and light rail any lighting provided must meet the minimum maintenance illumination levels in the notes to clause 19.1 of AS 1428.2 (1992) and should be at least 150 lux at the entrance and where a passenger pays the fare. Internal lighting on a conveyance may be dimmed as required to stop reflections interfering with the operator's vision.
